Explanation:

Boa constrictor: 30 years

Boa constrictors are native to North, Central, and South America, mainly dwelling in rainforests. The lifespan for the large, heavy-bodied snake averages about 20 years in the wild, but living in captivity can increase that by 10 to 15 years.

Answer: Some types of snake can live for 2-3 decades, such as the boa constrictor, whereas others, such as garter snakes, will be fortunate to reach 10 years of age. On averge a  snack changes its skin up to 2-4 times a year.

Explanation:

The label A represents mitochondria.

The mitochondria are also called the powerhouse of the cell which converts glucose to energy-rich molecules of ATP.

Label B represents the nucleus.

The nucleus contains the genetic material or DNA, RNA, nucleolus, chromatin fibers, and proteins. It contains the chromosomes which control the hereditary characteristics.

Label C represents the lysosome.

Lysosomes contain digestive juices which break down large cell parts and large molecules and help in intracellular digestion.

Label D represents rough endoplasmic reticulum having ribosomes.

The rough endoplasmic reticulum provides a surface for protein synthesis. It is also used to transport cellular contents from one cell to another.

Complete question:

Both species of garter snakes prey on the California newt. Taricha torso, small amphibian that produces a potent neurotoxin (TTX) in its skin. However, neither species of garter snake is affected by TTX. The resistance to TTX is associated with mutations in the SCN4A gene. which of the following best supports a claim that TTX resistance arose independently in T. atratus and T. sirtalis?    

A. The stomach contents in fossils of both species include the remains of food items that contains TTX.

B. Both species of snakes possess the SCN4A gene.

C. The two species of snakes have different genetic mutations in the SCN4A gene.

D. T. atratus and T. sirtalis are sister species that share many of the same morphological features.

Answer:

C. The two species of snakes have different genetic mutations in the SCN4A gene.

Explanation:  

These are two different species that feed on the same amphibian species and that developed resistance to TTX. Resistance to the toxic is associated with mutations in the SCN4A gene. So probably both species by separated developed different mutations in the gene that led them to be resistant to the toxin.

Supporting the fact that natural selection is not random, both species might have become resistant to TTX through different mutations in the same gene. Both species are feeding on the California newt that produces neurotoxin in the skin. Animals that feed on this amphibian need to be resistant to the toxin to avoid death and keep preying. TTX might be acting as a modeling pressure that led snakes to develop resistance to the toxin, favoring the same phenotype but independently.

A. The stomach contents in fossils of both species include the remains of food items that contain TTX. → Food items with TTX in the stomachs do not mean that species were resistant to the toxin. And if they were, it does not mean that species developed the resistance independently or not.

B. Both species of snakes possess the SCN4A gene. → The fact that both species have the gene does not mean that they have mutations in the gene

C. The two species of snakes have different genetic mutations in the SCN4A gene. → That both species have different mutations in the same gene means that they evolved independently from each other. They suffered different mutations in the same gene that led them to express the same resistance phenotype.  

D. T. atratus and T. sirtalis are sister species that share many of the same morphological features. → Morphological features do not necessarily reflect molecular features. The fact that they are similar sister species does not say anything about the SCN4A gene.

The condition that best supports this experiment is the two species of snakes have different genetic mutations in the gene described above.

Mutations may be defined as sudden, stable, and inheritable changes in the genetic material of an organism.  

Both species of snake have different mutations in the same gene means that they evolved independently from each other. They undergo different mutations in the same gene that led them to express the same resistance phenotype.

Therefore, the condition that best supports this experiment is the two species of snakes have different genetic mutations in the gene described above.

Answer:

An outbreak of a disease that infects squirrels in the park.

Explanation:

All the other answer choices would increase the population of squirrels. For the first option, more trees = more habitats = more squirrels to live in. For the second option, less hawks = less predators = more squirrels that will survive. For the third option, heavy rain = more acorns = more food for more squirrels.

Only the last option would limit the growth of a population of squirrels since diseases kill organisms in a population.

Explanation:

Brine pools are sometimes called sea floor "lakes" because the dense brine does not easily mix with overlying seawater. The high salinity raises the density of the brine, which creates a distinct surface and shoreline for the pool. When submarines dive into brine pools, they float on the brine surface due to the high density

Answer:

Explanation:

Plantae and Fungi are two of the three main kingdoms in the domain Eukaryote (the third group is Animalia, which includes you and me).

Many fungi grow in a way that’s similar to plants. They inhabit similar ecosystems and may even form symbiotic relationships together. Mycorrhizae are fungi that grow on the roots of plants, helping the plants take up nutrients in the soil while the plant provides the fungus with sugar. Of course, most fungi don’t look much like plants.

But the differences between fungi and plants are more than just skin (or bark) deep. While mushrooms often inhabit similar ecosystems to plants, molds and yeasts are even more different from plants!

Looking at a plant cell and a fungi cell under a microscope will reveal some interesting similarities and differences.
